American Hydroponics Dark Energy, 16 oz (AH88011) Not for sale in Oregon Dark Energy is a select blend of L-amino acids, specifically chosen for each of their beneficial effects on plant growth. L-amino acids improve the absorption rate of your favorite fertilizers by chelating essential nutrients and making them more available to your plants. Dark Energy enhances the bloom stage of any plant by stimulating the natural production of ethylene, a flowering and ripening hormone. Trials have shown that an increase in ethylene concentration results in a reduced time to harvest and synchronized, even ripening. You will notice an increase in overall biomass and harvest quality through continued use of Dark Energy.
